Is there any way to apply language tags or datatypes to SMS2 mappings? Is there maybe another argument to a template that I can use? I've tried STRDT nad STRLANG in various places with no luck and various incantations of templated strings.
I know the docs say that the only functions supported are template and datatype casts but I was wondering there might be some multi-arg template function or something.
If not do I need to drop back to SMS or maybe ever R2RML?

In SMS2, you can cast to an XSD type using the standard cast function in the BIND, eg `bind(xsd:integer(?field) as ?fieldInteger)`. We haven't yet added support for `strdt` and `strlang` in SMS2.
